After purchasing the latest Humble Bundle I have an extra copy of the first Torchlight, which apparently is tradable on Steam. Anyone who wants it, I need an email address and since I have only one extra copy it's on first come basis.
Reply or PM the necessary info.
Everyone I know with a Steam account already has it.
Edit: I realize I used the word trade, and only cause that's what Steam calls it. I am just giving this away, I don't expect anything back.
